Explanation:

Step1: Determine the electron configuration of Li atom

The atomic number of Li is 3. The electron configuration of Li atom is \(1s^{2}2s^{1}\).

Step2: Consider the formation of \(Li^{+}\) ion

\(Li^{+}\) is formed by losing one electron. Li atom loses the outermost electron (from the \(2s\) orbital). So the electron configuration of \(Li^{+}\) is \(1s^{2}\).

Answer:

\(1s^{\wedge}2\)
